 *
 * v0.6b (16.01.99) phx
 *       Changed copyright for 1999.
 * v0.5a (28.06.98) phx
 *       text "-w suppress warnings" was missing.
 * v0.4  (06.06.98) phx
 *       -sc forces merging of all code sections in an executable.
 *       -sd forces merging of all data and bss sections in an executable.
 *       -multibase prevents auto-merging of sections, which are accessed
 *       base-relative.
 * v0.3a (18.04.98) phx
 *       -baseoff was missing in help text.
 *       Updated some other help texts.
 * v0.3  (16.04.98) phx
 *       -R directs vlink to generate short relocs, if the target format
 *       allows this. It is for example supported by ELF and AmigaDos.
 *       Commented some options out, which are still not supported.
 *       -F for reading files, which contain a list of input files
 * v0.1  (27.02.98) phx
 *       First version that seems to link AmigaOS ADOS and EHF
 *       objects and libraries. Many common features, like linking
 *       sections together which have relative references, are
 *       still missing. Also, PowerPC-ELF32 support is about to come.
 * v0.0  (04.08.97) phx
 *       File created. Project started on a beautiful summer-day
 *       at the North Sea beach of Cuxhaven. :)
